The present invention relates to improvements in wall constructionandhas for its 7 V oniFigure 4 to disclose the manner'in which principalobject to provide a hollow wall which includes blocks or slabs ofpredetermined shapes that are arranged in such-a manner as to precludethe admission of cold air or moisture through the wall and at the sametime provide for a continuous air space or horizontally communicatingvertical air spaces between the inner and outer wall members'orsections. 7

Another important object of the invention is to provide a wallconstruction wherein the pre-cast wall blocks or slabs are adapted to bearrangedso as to form molds for reinforced concrete pillars or columnsthus obviating the necessity of having to employ wooden forms.

Afurther and important object of the in- 0 vention is to provide a wallconstruct-ion wherein certain of the'blocksor slabs may be employed asabase tosupport horizontally tion will become apparent from the'following description when taken in connection 1 with the accompanyingdrawings.

In the accompanying drawings wherein llke reference characters indicatecorresponding;

Figure 9 is a plan View of-a portion of a hollow wall wherein modifiedblocks are used. Figure 10 is a detail perspective view of the T-shapedunit that is employed in forming the modified wall structure'shown'inFigillustrating a furtherv modification ofhthe blocks. 1 I v t Figure.12 is a detail perspective view similar to Figure 10 of thesubstantially T shaped unit used in conjunction-with the wall structureshown in'Figure 11; and

Figures 13 and 14'show still furth'er forms of blocks which may be usedinlieuof the blocks of Figures 6v and 7 to form af wall in accordancewith this invention;

; In'the drawings whereinfor the purpose of 3 illustration isshown thepreferred embodiment of my invention, the numeral 1 desig- V nates asubstantially rectangular, shaped block or slab that maybe formed-of anysuitable composition. The numeral 2 designates an angular unitconsisting of a substantially T-shaped block that isemployed inconstructiii-g theihollowrwall, while 3 designates 'the right angularcornerblock. In constructing the hollewwail, a" series of bloeks 1are-ar ranged spaced relation "and the samerare positioned on t heirlower longitudinal edges inter esedtetw en the spaced-i riser 01E thiseater wall member ai-i the head portions 4 :of the-'T s'ha-ped blocksa.Tlie'inner wall theb'lcoks'of the innerwall member arespaeed retoriathe' euter of tfhewall and member will be spaced from theinn er face: ofthe opposed blocks 1 of thevouter wall member, whereby to form acontinuous air space or horizontally communicating vertical air spaces5. Furthermore, the joints in'the inner wall member will be out ofalinement with the oints in the outer wall member so that cold air ormoisture cannot pene-' trate through the entire wall structure, as willbe appreciated by those skilled in the art.

' The second course of blocks thatare arranged on top of the lowercourse are arranged in reverse order. That is to say the blocks 1 in theouter Wall member of the sec ond course will not be in verticalalinement with the blocks 1 of the lower course nor will the headportions 4 of the T-sh'aped units 2 be disposed in vertical alinementwith the head portions of the lower course so that the blocks inthealternate courses of the wall that is undergoing construction willonly be in alinement as is obvious from the construction shown in Figure4-. y

In constructing the corner of the building, it is necessary to employthe angular blocks shown in Figure 3 and these blocks are only used inalternate courses, the slabs or blocks 1 of the adjacent wallsformingthe corner portions of every other course.

The arrangement of the blocks in the manner as shown and describedprovides a mold for the concrete reinforcingpillars or columns 6 thatmay be reinforced through the medium of the vertically extendingreinforcing rods'T. This will obviate the necessity of having toemploythe conventional wooden forms as is now required in buildingconcrete structures having vertical pillars or columns.

Furthermore I utilize the rectangular shaped blocks or slabs 1 toprovidea base'for supporting the horizontally disposed concrete beams 8that may also be reinforced by the rods" 9 extending longitudinallytherethrough. In Figure 4, I clearly illustrate the manner in which theconcrete slabs or blocks 1 are employed to provide the base for theconcrete beams and it will be observed-that the blockspl are arrangedhorizontally to rest on the upper edges of the subjacent course ofblocks and T-shaped units and these horisupporting the cross sills orrafters shown at 11 in Figure 5. The end of the rafters or cross sillshave interfitting relation with respect to the blocks of the inner wallmember as clearly shown in Figures 4 and 5 and after the rafters orcross sills have been placed in position,

additional blocks are placed above the course modification of the hollowwall wherein the T-shaped blocks or units 16 have the heads thereofmerging with the leg portion through the medium of the tapered sides 17and the free end portion of the leg ofeach T-shaped unit shown in Figure11 has its sides beveled as indicated at:18.

Otherwise the blocks are arranged in the same relation with respect toeach other as the blocks shown in Figures 2 and 3.

It will thus be seen from the foregoing description, that I haveprovided a hollow wall construction that will be strong and durable andat the same time aiford the proper installation properties. ,Also byarranging the blocks in the manner as shownand described, the useof-wooden forms to provide molds for the vertical reinforcing concretepillars or columns is eliminated.

While I have shown the preferred embodiment of my invention, it isto beunderstood that minor changes in the size, shape and arrangementof'parts may be resorted to with-- out departing from the spirit of theinvention or the scopeof the appended claims.

Obviously, the U-shaped unit or block 19 of Figure 13 may be used withthe rectangular block 20 of Figure 14 in the manner taught in Figures 2and 3 and in lieu of the blocks 1 and 2, to form a similar wall. In alike manner, the angular blocks or units may take any one of many otherforms without departing from the spirit of the invention.

lVhat I claim is:

1. In a' wall constructionof the class described, inner and outer spacedwall sections, each includingcourses of blocks, each course comprisingspaced rectangular shaped blocks having angularly shaped grooves thereinand T-shaped units interposed between the spaced blocks having angularprojections for being received within the grooves, the outer faces ofthe heads of the T-shaped units lying-flush;

with the outer faces of the rectangular blocks, the leg portions of theT-shaped units being spaced from the inner faces of the opposedrectangular shaped blocks, the rectangular shaped blocks in the innerwall section being disposed in staggered relation with respect to therectangular shaped blocks in the same course of the outer wall section.

2. In a'wall construction of the class described, inner and outer spacedwall sections, each including courses of blocks, each course comprisingspaced rectangular shaped blocks having angularly shaped grooves thereinand T-shaped units interposed between the spaced blocks having angularprojections for being received within the grooves, the outer faces ofthe heads of the T-shaped units lying flush with the outer faces of therectangular blocks, the leg portions of the T-shaped units being spacedfrom the inner faces of the 0pposed rectangular shaped blocks, therectangular shaped blocks in the inner wall section being disposed instaggered relation with respect to the rectangular shaped blocks in thesame course of the outer wall section, the blocks in one course beingdisposed in staggered relation with respect to the blocks in the nextadjacent course. V

In testimony whereof I affix my signature.

FRED E. LEUZINGER.
